Material, design and engineering - all elements vital for pure signal transfer were technically investigated to provide the ultimate in reproduction quality. ESOTERIC power cord series - Hear everything as it was meant to be through components powered with ESOTERIC's high-end power cords!

Pure conductor / Stressfree annealing technology

ESOTERIC power cords incorporate high purity "Stressfree" copper conductors. The material purity of conductors used for critical areas is 7N (99.99999%) copper. This high purity material was originally developed for the semiconductor industry which requires an extremely high level of quality certification, and guarantees 7N purity with less-than-0.01 ppm (parts per million), of metallic impurities. This quality level is maintained by using 'GD-Ms' high precision material analysis technology. The high purity copper wire uses special "Stressfree" annealing technology to minimize distortion of the crystalline structure of the copper. These new power cords also feature extra-large crystalline structure conductor technology, "D.U.C.C." (Dia Ultra Crystallized Copper) in order to farther optimize the high purity and conductivity of the power path.

The 7N-PC7500 incorporates a newly designed IEC / Wall plug. This plug set features our highest quality silver + rhodium plated beryllium copper contact elements for ultimate conductivity and high mechanical strength that can withstand an 8 kg load. In order to control micro resonance, connector sleeves are precisely machined from solid aluminum and are quite heavy. Carbon fabric sleeves are attached to reject RF noise from entering the electric power path.
